An ammeter and voltage range are measure the current and voltage electric lamp if mistake meter interchange what will happen?
1. Voltmeter has high impedance and hence will restrict the current severely.a) Electric Bulb will not glowb) The Ammeter will just measure the current that Voltmeter allows and since this current is much smaller than actual current nothing will happen to ammeter.c) The Voltmeter will measure the Voltage that is being applied.d) This will allow you to measure the resistance of the Voltmeter.VR=V/I
Which current range on the Fluke 8025A do you select to measure 250 milliamps alternating current?
the AC-A ~A Range is safe, or for high resolution the mAµA~ range, if it is shure that there is no more than 300mA
Is led a voltage controller or current controller?
An LED is a diode that emits light; diodes allow current to flow only one direction. The voltage applied to the diode attempts to force current to flow in a specific direction. If the voltage polarity is reversed, and current was flowing before (so there was a small voltage drop across the diode), current will cease to flow (assuming the voltage is not too high for the diode to handle), and (almost) all the voltage will be dropped across the diode (a small leakage current may flow, which means some of the voltage will not be dropped across the diode, but this is in the milli or micro range). I would never define a diode as a "voltage controller" or "current controller". It could be either or both, from the above description.
Is 230 vac the same as 240 vac?
Neither. Line voltage can - and often does - vary from locality to locality. In the United States, you may find a wall-voltage spec'd at anything from 110v to 120v. The corresponding "220v" power would range from 220v to 240v. European voltages are very similar - falling in the range of 220 to 240v. Based on the load on the particular segment of the power-line your house is on, you can see variations of several volts - plus-or-minus - over the course of a day. 230 and 240 volts are a nominal figure in the same voltage range. It is brought about by the power company, as they have a responsibility to keep voltages within a certain 10% range. The load will only notice a difference of .5% on the load current. eg. Wattage load of 2400. Amps = watts/volts. 2400/230V = 10.43 amps. 2400/240V = 10 amps. On a constant resistance as the voltage goes lower, the current goes higher and vise versa as the voltage goes higher, the current goes lower.
Is 120 volts equal to 110 volts in a device?
Yes, 120 and 110 volts are a nominal figure in the same voltage range. It is brought about by the power company, as they have a responsibility to keep voltages within a certain 10% range. The load will only notice a difference of 1% on the load current. e.g. Wattage load of 1200. Amps = watts/volts. 1200/120V = 10 amps. 1200/110V = 10.9 amps. On a constant resistance as the voltage goes lower, the current goes higher and vice versa as the voltage goes higher, the current goes lower.

What instrument measures electrical earth resistance?
A multimeter device can measure resistance, current, AC/DC voltage, and it also can determine continuity on an electrical circuit, and its range for current, voltage and resistance is widely variable.
What DMV voltage range do you use to measure house current voltage 110V or 120V?
You must set the range so that the maximum value is greater than the conventional voltage levels in your house. Like, in the United States, the common voltage level is 120 volts RMS, although many homes are equipped with 240-volt service, to accommodate certain appliances, like clothes dryers. (The 240-volt service is really two 120-volt legs.) It's a good idea to set the range higher than expected initially.
Can you run 125v air conditioner on 120v house current?
Yes ,it's the same voltage.You have a +-5% of voltage range
How do you measure voltage?
Voltage can be measured using the difference between the potentiel between two ends of wire or by using a volt-meter. You can easily measure volt by volt or multimeter but remember voltage always measure across the components but in parallel
How do you test a Switched mode power supply using analog multimeter?
A: A VOM can measure the voltage across the load. To test the current if the current surpasses the VOM range just add a very small resistor in series with the load and use ohms law to find the current since you have the voltage drop.
Why you must put at highest range when you measure current or voltage?
You start at the highest range, because you don't want to damage the meter. You then bring the range selector down, incrementally, until the reading is in the lower, most accurate portion of the scale.
Will a fan requiring 230 volts ac run on normal house current?
Yes if the house supply is 220-240 volts. The required voltage range should be printed somewhere on the fan.
Is 122 volts for a house high?
No, 122 volts for a house is not high. It is a nominal figure in the same 120 voltage range. It is brought about by the power company, as they have a responsibility to keep voltages within a certain 10% range. The load will only notice a difference of 1% on the load current. e.g. Wattage load of 2400. Amps = watts/volts. 2400/240V = 10 amps. 2400/220V = 10.9 amps. On a constant resistance as the voltage goes lower, the current goes higher and vice versa as the voltage goes higher, the current goes lower.
It states how much change occurs in the output voltage over a certain range of load current values.Select one:a.Line Regulationb.Load Regulationc.Voltage Regulationd.Output change?
The correct term for the given description is "Load Regulation." Load Regulation refers to the measure of how much the output voltage of a device changes when the load current varies over a specific range. It quantifies the ability of the device to maintain a stable output voltage despite changes in the load.
How many volts make electricity?
If you use the definition of electricity as; The supply of electric current to a house or other building for heating, lighting, or powering appliances, then any voltage will fit into this range.
Why you use constant current source?
What follows below is not a full description. Full descriptions are in chapters of books about electronic power supplies.A constant current source is an electronic device which acts as a source of power whereby, however the load resistance changes - within a certain fixed range - the device is designed to monitor the output current drawn from it and will change its output voltage to keep the output current constant within a certain fixed range.Another answerA constant current source will provide constant current with a load if the load changes the volts will change to compensate for the constant current flowing. Which is just opposite to a constant voltage source whereby a load change will change the current but not the voltage. And that how it works.
